Hi,

I've found that modules built by python-cython with C++ could not be loaded.
If I understand correctly, the following patch fixes it.
Would you like to apply this patch to the package?

```
--- a/Cython-0.29.21/Cython/Utility/ModuleSetupCode.c
+++ b/Cython-0.29.21/Cython/Utility/ModuleSetupCode.c

 #elif PY_MAJOR_VERSION < 3
 // Py2: define this to void manually because PyMODINIT_FUNC adds __declspec(dllexport) to it's definition.
```

Thanks.
